Baby, It's You! And You, And You...

One obvious way is to point to the broader benefits. Thus cloning proponents like to attach themselves to the whole arena of stem-cell research, the brave new world of inquiry into how the wonderfully pliable cells of seven-day-old embryos behave. Embryonic stem cells eventually turn into every kind of tissue, including brain, muscle, nerve and blood. If scientists could harness their powers, these cells could serve as the body's self-repair kit, providing cures for Parkinson's, diabetes, Alzheimer's and paralysis. Actors Christopher Reeve, paralyzed by a fall from a horse, and Michael J. Fox, who suffers from Parkinson's, are among those who have pushed Congress to overturn the government's restrictions on federal funding of embryonic-stem-cell research.
But if the cloners want to climb on this train in hopes of riding it to a public relations victory, the mainstream scientists want to push them off. Because researchers see the potential benefits of understanding embryonic stem cells as immense, they are intent on avoiding controversy over their use. Being linked with the human-cloning activists is their nightmare. Says Michael West, president of Massachusetts-based Advanced Cell Technology, a biotech company that uses cloning technology to develop human medicines: "We're really concerned that if someone goes off and clones a Raelian, there could be an overreaction to this craziness--especially by regulators and Congress. We're desperately concerned--and it's a bad metaphor--about throwing the baby out with the bath water."
Scientists at ACT are leery of revealing too much about their animal-cloning research, much less their work on human embryos. "What we're doing is the first step toward cloning a human being, but we're not cloning a human being," says West. "The miracle of cloning isn't what people think it is. Cloning allows you to make a genetically identical copy of an animal, yes, but in the eyes of a biologist, the real miracle is seeing a skin cell being put back into the egg cell, taking it back in time to when it was an undifferentiated cell, which then can turn into any cell in the body." Which means that new, pristine tissue could be grown in labs to replace damaged or diseased parts of the body. And since these replacement parts would be produced using skin or other cells from the suffering patient, there would be no risk of rejection. "That means you've solved the age-old problem of transplantation," says West. "It's huge."
So far, the main source of embryonic stem cells is "leftover" embryos from IVF clinics; cloning embryos could provide an almost unlimited source. Progress could come even faster if Congress were to lift the restrictions on federal funding--which might have the added safety benefit of the federal oversight that comes with federal dollars. "We're concerned about George W.'s position and whether he'll let existing guidelines stay in place," says West. "People are begging to work on those cells."
That impulse is enough to put the Roman Catholic Church in full revolt; the Vatican has long condemned any research that involves creating and experimenting with human embryos, the vast majority of which inevitably perish. The church believes that the soul is created at the moment of conception, and that the embryo is worthy of protection. It reportedly took 104 attempts before the first IVF baby, Louise Brown, was born; cloning Dolly took more than twice that. Imagine, say opponents, how many embryos would be lost in the effort to clone a human. This loss is mass murder, says David Byers, director of the National Conference of Catholic Bishops' commission on science and human values. "Each of the embryos is a human being simply by dint of its genetic makeup."
Last week 160 bishops and five Cardinals met for three days behind closed doors in Irving, Texas, to wrestle with the issues biotechnology presents. But the cloning debate does not break cleanly even along religious lines. "Rebecca," a thirtysomething San Francisco Bay Area resident, spent seven years trying to conceive a child with her husband. Having "been to hell and back" with IVF treatment, Rebecca is now as thoroughly committed to cloning as she is to Christianity. "It's in the Bible--be fruitful and multiply," she says. "People say, 'You're playing God.' But we're not. We're using the raw materials the good Lord gave us. What does the doctor do when the heart has stopped? They have to do direct massage of the heart. You could say the doctor is playing God. But we save a life. With human cloning, we're not so much saving a life as creating a new being by manipulation of the raw materials, DNA, the blueprint for life. You're simply using it in a more creative manner."
